ROW_FORMAT=COMPRESSED unnecessarily requires NOCOPY for INSTANT operation

    Details

      Description

      create table t1(c varchar(9)) engine=innodb row_format=compressed;
      insert into t1 values (repeat('a', 9));
      alter table t1 modify c varchar(10), algorithm=nocopy;
      

      In this ALTER TABLE only data dictionary and cache are updated. So, in fact it's an INSTANT operation.
